Description

Why we love it:
A leave-in miracle worker, the K-18 Leave-In Molecular Repair Hair Mask restores damaged strands in just four minutes—no rinse needed. Whether your hair has been stressed by bleach, colour, heat, or chemicals, this revolutionary formula brings it back to life with strength, softness, and bounce.

How it works:
Powered by K-18’s patented peptide technology, this mask travels deep into the hair’s core to reconnect broken keratin chains, reversing damage at a molecular level. Unlike traditional conditioners that simply coat the hair, this formula rebuilds from within—delivering lasting repair and renewed elasticity.

How to use:
After shampooing, skip the conditioner and towel-dry hair thoroughly. Apply 1-3 pumps, depending on hair length and thickness, working it through from roots to ends. Wait four minutes for the peptide technology to activate—then style as usual. No rinsing required.

From the experts:
"Think of this as rehab for your hair—strengthening and restoring each strand from the inside out for lasting resilience and shine."
